Answer:
The probability of the student will pass the quiz = .0546
Step-by-step explanation:
Given -
Total no of question = 10
If the student guesses on each question there are two outcomes true of false
the probability of guesses question correctly = 
the probability of success is (p) = 
the probability of guesses question incorrectly = 
the probability of failure is (q) = 1- p = 
If the student guesses on each question he must answered at least 8 question correctly
the probability of the student will pass the quiz = 
= P(X = 8 ) + P(X = 9) + P(X = 10 )
= 
= 
= 
= 
= .0546
